A near-perfect financial health score and solid momentum point to a sound underlying business, but the stock has reached its analyst consensus target, forward multiples are stretched relative to growth, and a 2.6-to-1 put/call ratio suggests the options market is positioned for near-term downside.

About Clean Harbors, Inc.
About Clean Harbors, Inc.
Clean Harbors operates ten commercial hazardous waste incinerators — including the newest facility in Kimball, Nebraska, which commenced operations in late 2024 — along with seven landfills and a fleet of more than 20,000 vehicles across North America. In 2025, the company collected 243 million gallons of used oil through its Safety-Kleen Sustainability Solutions segment. The Environmental Services and SKSS segments together serve customers spanning general manufacturing (14% of 2025 revenues), chemical (14%), refineries (12%), automotive (10%), and utilities (7%).
Clean Harbors earns fees for collecting, transporting, treating, and disposing of hazardous and non-hazardous waste — services sticky enough that customers must audit disposal facilities and limit their approved vendor lists due to liability exposure under U.S. and Canadian environmental law, creating meaningful vendor-switching barriers. The Environmental Services segment results are driven by waste volumes, industrial project demand, and unplanned emergency response events including chemical spills and natural disasters; the company maintains more than 150 emergency response locations. The Safety-Kleen Sustainability Solutions segment collects used oil, re-refines it into base oil and vacuum gas oil (VGO) at the company's re-refineries, and sells back into the lubricants market; SKSS segment results are significantly impacted by market pricing of oil products. The company actively manages used-oil collection pricing as a strategy to manage re-refinery spreads. Portions of the business connected to automotive services — including parts washer and vacuum services through Safety-Kleen branches — are exposed to automotive industry miles-driven and maintenance trends. The company has executed over 80 acquisitions throughout its history.
Show full overview
Clean Harbors recorded closure, post-closure, and remedial liabilities valued at $230.7 million at December 31, 2025, substantially all assumed through prior acquisitions. The company was also involved in 76 product liability proceedings related to Safety-Kleen parts washer services as of December 31, 2025, with claimants alleging personal injury from solvents containing benzene. Changes in environmental regulations — particularly those addressing PFAS, which Clean Harbors has responded to with its Total PFAS Solutions service — may increase compliance costs but could also generate new disposal and remediation revenue, presenting both risk and opportunity as this regulatory landscape evolves.
